To all wizorn. it may concern:

Be it known that we, WILLIAM WALLACE Kniur and VVILLIAM H. Var: H'oRN, c tizens of the United States, 'residingat Baltimore,

in the State of Maryland, have invented new and useful Improvements in Burners, of which the following 15 aspecificatlon.

This invention relates generally to gas burners, but more particularly to the'tips or nozzles therefor, and has for its object to' uniform flame throughout the series or bat-- tery-of tips upon. the pipe-manifold.

In carrying out this object the invention comprises broadly a .nozzle having a gas collecting chamber communicating through a very small passage or perforation with the manifold from whichthe gas is supplied, a plug with narrow slits seated in the nozzle and closing the outer end of the collecting chamber, and a combustion chamber in the nozzle beyond the plug in which the ignition of the gases issuing from the plug takes lace.

p The invention contemplates, further, the peculiar construction of the nozzles whereby thecombustion chambers of the same, when the nozzles are'arranged close together burning a continuous narrow sheet of flame is produced, and the entire line of nozzles is kept ignited.

The invention also embraces means for adlisting the width of the sheet of flame of the w of tips to accommodate cloth, cans -and :l e like varying in width, such meanscom- 'ing valves or the like for cutting oil the of the burner. Fig. 2 is an end elevation of the same. Fig. 3 is a detail, enlarged, fragmentary, sectional. view of the burner. Fig.

ow oi gasto any desired number of the 8*- is a detail longitudinal section through one of the end nozzles or tips taken at right angles to the showing in Fig; 3. Fig. 5lis-a.

transverse sectional view through the burner takemmentrally through one of the. nozzles and showing the soft flame produced. Fig. 5 1s a 'similar view disclosing a slightly'different' form of plug and the thin needle flame produced. Fig. 6 is a top plan view of one end of the burner showing a slight modification in the arrangement of the nozzles or tips,the same shown in staggeredrelation.

Fig.7 is a detail fragmentary, sectional, enlarged view of the burner showing a modilied form of tip or nozzle applied thereto.

Similar characters of reference designate corresp'ondingparts throughout the several views of the drawings.

In the accompanying drawings showing the present embodiment of the invention the numeral 10 ydesignates a pipe-manifold shown as cylindrical in form although any desired shape may-be given the same. This manifold: 103s threaded at one end 11, for attachment to a suitable source of gas supply, maybe of any desired length, and is closed at its outer end in any suitable mannor, as by a cap 10 shown in Fig. 1. In one side. of the manifold 10, preferably the upclosely arranged tips or nozzles 12 through which the gas issues. from the manifold 10.

per side, as shown, is a longitudinal row of With special reference to Fig. 3 of the drawings, it will he noted that each tip or nozzle 12 comprises a cylindrical casing pro-- viding therein a gas collecting chamber and being reduced at its inner or, lower end to provide a supporting shank or neck 13 commu-nicating with the interior of the casing.

Thellower end of the neck 13 is threaded or otherwise suitably secured in the side of the manifold 10, and is closedat its lower end by a disk 14 preferably formed integrally with the nec 13 having but a single small passage or perfioratio'n, 15 extending centrallytherethrough. The perforation 15 is the sole sollrqe of communication between the interior o f the manifold 10 and the gas collectin izhamhenin the casing, and the perforations 15 are of uniform size through out the entire line of nozzles.

The casing of the tip or nozzle 12 is provided in its outer end with a counterbore,

'wherehy to provide a shoulder 16 upon can collecting chamber and is provided with a plurality of radially extending and relatively narrow slits, the slits extending from face to face of the plug and from a point near the central. axis of the, plug to the periphery thereof. The casing of the nozzle 12 is carried beyond the outer face of the plug 17 to provide a combustion or ignition chamber in the outer end of the nozzle.

In Fig. 1. of the drawings it will be seen that the nozzles or tips 12 are arranged in a straightrow from end to end of the manifold 10, and in Fig. 6 of the drawings the nozzles are shown as arranged in a row but in staggered relation to one another. For the purpose of interconnnunicating the ignition or combustion chambers of the nozzles, the'casings of the nozzles 12 are cut away at their outer ends and adjacent sides to provide recesses 18 diametrically opposed as shown in Fig. 1, or arranged at angles to one. another at 18 as shown in Fig. 6. In both instances the recesses 18 are formed in the acent or touching sides of the nozzles st) that the combustion chambers of the entire line of nozzles are\ n communication with one another. It will, of course, be understoodtl'rat the end nozzles are provided with uninterrupted walls 18?, as shown in Figs. 1 and 6 on the nozzles located at the ends of the manifold.

To admit the, reducing of the width-of flame orthc length of the flame longituiilinally of the manifold, any desired number of the nozzles or tips 12 at each, end of the manifold are provided with valves or the like admitting the cutting off of the gas to these end nozzles or tips. In Figs. 1 and 2 of the drawings the five last nozzles or tips 12 at each end of the manifold 10 are provided with needle valves 12 having en.-. larged heads on their outer ends for engagement by the fingers to regulate the valves, From Figs. 3 and 3 it will be seen that the needle valves 12 are threaded through one side of the necks 13 of the noz zles or tips 12, project across the openings in the lower ends of the, necks 12-3 and, when closed. fit into the recesses or seats 12 formed in the opposite sides of the necks 13. The valves 12 are of a thickness su'tlicient to cmnpletely close the openings through the necks 13 and completely shut oil the flow of gas to the tips 12. If desired the entire line of tips 15? may be provided with these valves i 13 as to regulate the flame across the entire line of tips.

From Figs. 3 id il it will he noted that in the preferred construction the plugs 17 have impcrforate central portions, the same providing an. abutment for the stream of gas passing up through the small perforatimi 15,

and alsoprevmitiug the needle-like formation of the flame burning a.t.the nozzle. I 'lhis'type ot burner nozzle is peculiarly adapted for use for singeing cloth since the flame produced, as seen in Fig. 4, is a soft tapering flame relatively thick and, when the burners are arranged in a row as shown in Figsl 1 and 6 they produce a relatively long uninterrupted sheet of flame.

From Fig. 5 of the drawings it will be noted that the plug 17 may have a. central or axial perforation 19 through which the gas issues in a line stream. This fine stream of gas when ignited produces a needle-like flame which draws in or collects the radial film of gas issuing from the plug so that the entire flame has the appearance \shown in Fig. 5 of: the drawings wherein a very narrow and elongated flame of needle-like appearance is produced. When these burners, shown in Fig. 5, are arranged in rows as shown in Figs. 1 and 6, the result will be a row of closely arranged needle-like flames.

Should for any reason the flame cease to burn in the combustion chamber of any one of the nozzles and the supply of gas continue to flow through the nozzle, the gas will a ain iunnediately become ignited by the en "railing of the gas through the adjacent recesses 18 in thesides of the' ombus tion chambcrs.- Thus the burning o'f'ttll of the nozzles or tips in the row is insured during the operation of the burner.

In operation the gas in the manifold 10 passes through the relatively small perforations 15 in the tips of the burners l2 and into the gas collecting chambers in the *asings thereof, the perforations 15 being of uniform size throughout the line of burners insures a uniform distribution of the gas throughout the entire line of burners. In the chamber of each of the burners 12 the gas is permitted to expand and the stream of gas issuing from theperforation 15 cannot strike the burner plug or disk 17 at one point with any greater force than at another so that the flame will be uniform'over the entire area of each tip and the entire line of nozzles. The collected gas within the casing 12 passes upwardly and outwardly through the relatively. narrow slits in the plug 17 and passes into the combustion chamber of the nozzle in fine sheets or films. lVhen in action, these thin sheets or films of gas are ignited in the combustion chamber, and since the central or middle portion of the plug 17 is solid or imperforate a flame such as disclosed in Fig. 4 will be pro duced.

When the plug 1.7} shown in F is. 5 is used in the nozzle of "tip. then the gas issues through the relatively small central perforation 12) in athin jet -d awing into it, the surroundingfilms of gas issuing through the slits in the plug 17- Thus the needlelike flame of Fig.5 is produced. V

In Fig. 7 of the drawings is disclosed a modification in the structure of the burner nemesis r in the side of the'iie'c" 13 through which gas the line of flame to accommodate cloth vary passes into the-nteck andthrough. a narrow passage 20 leading fromthm lower end of the, gas collecting chamber in the casing 12 v the body of the nozzlebei-ng provided'with a valve seat at the lower end of the passage 20 adapted to receive a needle valve 21 carried upon the upper end of a screw plug 22 threaded in the lower end of the neck orv stem 13 As willbe seen from Figs the stem br' neck 15 opens through the bottom of the manifold 1Q such arrangement being had whereby-easy access may be gained to thescrew plug 22 for adjustingthe sizeof the flame while burning. With,this modified arrangement or 'additionto the preferred torm. of burner, the entire line of flame may be adjusted to the desired height; so that in, any class ofmachine or work'in which it is desirabl to' tapercr incline the flame,'or vary the intensity of the heat at the l ne of flame, this may be any point in done.

Whenit is desired to reduce the width of ingin width, it is only necessary to close the valves 12 of the desirednumber of the end tips 12 at each end of the manifold v i It is of course understood that various changes or modifications may be made in the structure of the burner to suit the conditions under which the burner is to be used, such changes or modifica'tiom; being comprehended in the scope of this invention as defined in the appended claims.
